Abstract: A method of regioselectively and stereoselectively synthesizing forskolin (8,13-epoxy-1 alpha ,6 beta ,7 beta ,9 alpha -tetrahydroxylabd-14-en-11-one) from 9-deoxyforskolin (8,13-epoxy-1 alpha ,6 beta ,7 beta ,-trihydroxylabd-14-en-11-one) with a good yield is described. In a preferred embodiment, it comprises an enol ether formation from 8,13-epoxy-1 alpha ,6 beta ,7 beta -trihydroxylabd-14-en-11-one-6,7-carbonate, oxidation of the enol ether with a suitable peroxy acid to obtain 11,12-dehydro-8,13-epoxy-11-methoxy-1 alpha ,6 beta ,7 beta ,9 alpha -tetrahydrolabd-14-ene-6,7-carbon ate and hydrolysis of the latter under an acidic condition to obtain 8,13-epoxy-1 alpha ,6 beta ,7 beta ,9 alpha -tetrahydroxylabd-14-en-11-one-6,7-carbonate. As an alternative way of protecting the two hydroxy groups at carbon-6 and carbon-7, they may also be converted to dimethyl acetal during the synthetic sequence. Four compounds produced in the synthetic scheme as intermediates, namely, 9,11-dehydro-8,13-epoxy-11-methoxy-1 alpha ,6 beta ,7 beta -trihydroxy-labd-14-ene-6,7-carbonate and 11,12-dehydro-8,13-epoxy-11-methoxy-1 alpha ,6 beta ,7 beta ,9 alpha -tetrahydroxylabd-14-ene-6,7-carb onate and the corresponding dimethyl acetal compounds are believed to be novel.

Abstract: A process for separating special steel components from lump shredder scrap includes first removing the ferromagnetic content from the shredder scrap and thereafter dividing the shredder scrap into a normal size fraction and an undersize fraction. The undersize fraction is then treated by separating the special steel content from the undersize fraction by a magnetic drum having a field strength above 0.2 tesla.

Abstract: Each input line (a, b) to the subscriber circuit (SLIC) has a solid state line switch (La) and solid state test switches (STa1, STa2).  To protect the line switch, the test switch (STa2) close to the equipment (SLIC), and the equipment itself a voltage surge diverter is connected in front of the line switch.  It comprises a low ohmic value resistor (RS1), typically of 50 ohms, and a four layer, or thyristor diode (DT1) connected between line and earth. To improve the integrity of the outer test switch (STa1) it is separately protected with a thyristor diode (DT2) across the switch and a resistor (RSZ) in series.  A further thyristor diode (DT3) connects the circuit to earth.  The latter diode (DT3) can be common to many input lines. Conventional line protection using two diodes (D1, D2) can be connected at the immediate input to the equipment (SLIC).

Abstract: According to the invention, the shaped bodies are comprised of at least one heavy metal, preferably Fe, Ni, Co, Sn, Mo or W which can be reduced from a corresponding metallic compound at a temperature of less than 1 500° C. The shaped bodies have an outer diameter ranging from 0.05 to 0.5 mm, and a diameter-to-wall thickness ratio of 0.5 to 3%. According to the method, starting materials are deposited as an enveloping layer on supporting elements of any shape, and the green compacts thus produced are subsequently heat-treated. On that occasion, the supporting elements are pyrolyzed, the enveloping layers are essentially thermally decomposed and the decomposition products are sintered. The outer dimensions of the supporting elements are selected such that they are larger than the shaped bodies to be produced. Metallic compounds, preferably metal oxides, metal hydroxides, metal carbonates or organometallic compounds are used as starting materials and can be reduced at a temperature of less than 1 200° C. The thermal treatment is carried out in a reductive atmosphere containing hydrogen and/or carbon such that the starting materials are essentially reduced to the sintered metal which is based on the respectively used metallic compound.

Abstract: The invention relates to a method for producing elongate-shaped elements, such as wires, rods and pipes made of magnesium or magnesium alloys by slip-type drawing at room temperature.  The aim of the invention is to develop a method which enables magnesium wires, rods and pipes to be produced by cold-drawing.  According to said a method, this is achieved by subjecting the materials to surface treatment before the deformation thereof, guaranteeing a surface roughness which is as low as possible, the value of the average surface roughness being Rz < 12  mu m.  The cold-adherent is carried out by using solid-adherent lubricant coatings on the deformation items.
